Given the horribly moist winter we’ve had, guests needs to be flocking to see the Flood Resilient Garden at this yr’s RHS Chelsea Flower Show.
Designers Naomi Slade and Dr Ed Barsley are creating the backyard to show how to assist scale back flood danger and to get well shortly after intervals of heavy rainfall, in addition to offering helpful concepts to future-proof our gardens and scale back the devastation that flooding brings.
Their backyard will characteristic dense planting to gradual the circulate of water, in addition to capturing and storing water, and channelling rainwater right into a pond, the place it can steadily soak away. Adaptable pond and bathroom crops may also be included.
“Our gardens are part of our homes and we are very connected to them. Preparing them to cope with anything the weather can throw at them therefore makes sense, as it is important that they remain useable and enjoyable,” says Slade.
“Flood Re: The Flood Resilient Garden has been designed on a relatable domestic scale and it is packed with ideas, which can be used in visitors’ own gardens. From capturing and storing water, to managing soil so that it becomes an effective sponge for excess water, to choosing the right plants and being creative about the landscape of the garden itself, there is something here for everyone.”
Slade provides suggestions to assist alleviate flood injury to gardens and provides them one of the best probability of restoration.
Choose resilient crops that can come again
“Some plants traditionally seen as pond marginals, such as marsh marigold (Caltha palustris), are often far more resilient than people realise and can cope in ephemerally wet places,” says Slade.
Choosing the precise cultivar can make a giant distinction. For instance, Geum rivale likes damp shade, whereas Geum chiloense will take a drier and sunnier spot. It additionally is smart to capitalise on tough damper spots, planting shrubs comparable to amelanchier, which isn’t a fan of actually dry circumstances, or turning an actively boggy space right into a rain backyard, she suggests.
Avoid plastic grass
“A popular but destructive garden fad, plastic grass is sold as an attractive, low-maintenance option, but it doesn’t deliver in the long term, and it is certainly not flood-friendly,” says Slade.
“When it is laid, the soil is compacted, which means that rainwater struggles to penetrate and much of it will run off the surface. The hairy finish provides no food or living space for wildlife, and the blanket of plastic and membrane isolates the ground beneath so little can live there. Real lawns, large borders and permeable surfaces are a far better option.”
Cut down on laborious landscaping
While outlined paths and dry ft are a bonus within the again yard, laborious surfaces imply that heavy rain has nowhere to go. Where there’s plenty of paving, or tarmacked areas are in depth, rainfall might accumulate to trigger native flooding, so intersperse strong slabs with gravel or planted areas, or create deliberate soak-aways, she advises.
Store water
The flip aspect of rain is drought, and water butts and storage options comparable to tanks are featured in The Flood Resilient Garden, which serve a number of functions. In moist intervals, they seize water, which helps scale back the burden on the sewers and downstream flooding.
When the climate dries up, the saved water can be used to maintain the backyard lush, inexperienced, wholesome and resilient, and it saves cash on faucet water, too. Water is a problem however additionally it is a useful resource, so don’t waste it.
Improve your soil
Soil is made up of particles with air areas in between, and when it rains, these refill with water that can drain away steadily. Where soils are compacted by trampling and in areas of heavy clay, the air areas are small, drainage is poor and water can accumulate on the floor.
Spreading natural matter, comparable to leaf mould or spent potting compost, and permitting plant detritus to rot away naturally, encourages a wholesome underground ecosystem. This improves the construction of the soil, and makes it simpler for water to sink in.
Plant abundantly
“As a nation of gardeners, we love herbaceous perennials and lawns, but relying on plants that die back in winter or that lack diversity and are kept artificially short by mowing, means that the garden is not operating at its flood-resilient best.
“Allowing dense growth and leaving stems long in winter will help slow the passage of surface water, while shrubs and evergreens capture a surprising amount of rain in their canopies, meaning that it doesn’t all reach the ground at once, and they add attractive structure too,” says Slade.
